Method and devices for forestation and flood prevention

ABSTRACT

With the present invention, sand storm disasters will no longer occur in Beijin and the Hubui province in China and the water of the Yellow River will be clear; soil erosion due to flood in the United States and Europe will decrease. The invention utilizes the sand, soil and gravel of the earth to cure its illness. Such normally useless natural materials are filled in plastic bags to form flexible soft sand bricks, and they are laid on the ground to stabilize sand for growing vegetation or to prevent soil depletion due to water erosion. With the present method, sand and soil are stabilized to the condition similar to that grass has already grown on them for five years and trees have already grown in them for ten years. It can thus be used surely for carrying out forestation all over the world; forestation may even be carried out in barren area in the United States so as to have rich forests throughout the country; and the area around the Wufoo water dam will recover to its past beauty. The tree planting bullet of this invention may be used with planting guns firing them from the air or with water guns firing them on land to facilitate tree planting, such that corporations in the forest industry will no longer hesitate to carry out reforestation in regions destroyed by forest fires, due to the devaluation of their company shares. The invention may be used to change the environment of the Middle East to favorable for living so that it may have ever lasting peace. The soft sand bricks of the present invention may be used to grow vegetation in the desert for conquering the normal difficulty in its forestation. Forestation is important since it can mitigate flood disaster, drought, and sand storm in the desert; and it can be realized inexpensively with the use of the soft sand bricks and the planting bullets of the present invention. Therefore, it can prevent the further deterioration of the earth. The countries and regions indicated above are for illustration only.

BACKGROUND OF THE INVENTION

[0001] This invention relates to a method and system for improving the global environment.

[0002] People are increasingly aware of the changes in the global weather pattern from that of the past. Pollution of the environment is worsen with the annual ever increasing demands for more crude oil and the creation of industrial acid fluid wastes. People in Canada and other parts of North America are warned to stay out of the mid day sun in the summer to avoid being harm by the high level of UV ray passing through the hole in the ozone layer. Economists have long warned that the world economy is on a deteriorating track; nonetheless, in combating poverty and in seeking for affluence or better health care, changes must be made to restrict the source of pollution. Yet, in fact, in order to eliminate millions from dying of starvation in the present economic and monetary system, people around the world would have to suffer from more pollution. This is evident by the diminishing amount of forest world wide. When viewing a documentary showing how a hundred year old tree could be fell within several short minutes, one could not help but to shudder at the power of the almighty dollar driving man to destroy the environment in such a reckless manner to obtain more monetary gain. Some effort has been spent in re-forestation in which seedlings are carried in bags by people climbing up a mountain side to plant them; however, it takes many years for a tree to grow to maturity from a seedling. A land that is not protected by trees is subject to soil erosion. The eroded soil eventually ends in rivers to cause water blockages which in turn cause flooding; and flooding causes yet more soil erosion and more blockages in the river. Often, in flood, water would bypass hydro dams to seek for faster routes to flow out to the sea or lake, and it carries with it the soil and invariably the soil protective plant and grass, thus the water source is depleted in an even more faster rate. Thus, flood occurs more frequently and more seriously world wide. Drought may follow after a flood, because the land after the flood would lose its water retaining property due to leaching by the flood water. The leached soil is not suitable for plant growth either by natural means or by manual planting; and rain water, if any, subsequently falling on such soil would simply run off quickly to result in that the water levels in the lakes and rivers are abnormally low during the drought, or are overflowing by the excessive amount of water flowing into them swiftly during the flood. Such phenomenon is lamented by fishermen due to the loss of the fish stock. Rivers and streams are similar to the heart and arteries of a human body, their blockage has serious consequences. Medicine corrects an artery blockage by using an artery expansion balloon, or by bypass surgery conducted with a vein removed from another part of the body, or reviving the heart with a defibrilator, similarly science and engineering must cure the defects of the earth with new planting methods to prevent flood, drought, soil erosion and water run off. This is the most important object of the present invention. God created the earth. River and stream are the result of the accumulation of droplets of water from rain. Modern engineering may provide advanced techniques but it often lacks diligence. It tends to solve a defect by correcting the defect per se rather than curing its cause. The present invention provides the combination of plastic bags with the soil and sand world wide for preventing the soil erosion due to wind or flood. It provides a method of creating a soft or flexible brick which eliminates the deficiencies in the common use of steel reinforcement, concrete, rock, clay brick, and fire baked brick for such purposes. With the stabilization of the soil and sand that are not affected by flood or drought, vegetation planting can be effectively carried out. The vegetation would, in turn, improve the soil; and it would flourish with roots growing deeper into the soil as well as providing richer foliage to shading the ground so as to improve further its water retaining property. Due to the differences in the amount of rainfall, ground and soil formation, and factors in the working environment, the following various methods are provided by the present invention to achieve these purposes:

[0003] (1) Device with dripping water supply: In a windy area, a tent-like protective plastic shield or housing is firmly anchored on the ground with sand piles. The housing creates a rain forest environment within it while providing the air required for growing a tree in such a protected environment. After the tree has grown to maturity and is capable of withstanding the severe environment outside of the housing, the tree would inherently break the latter. The grown tree would subsequently provide shading and protection to the sand and soil it grows on.

[0004] (2) For dry land in a semi-desert area, seeds and tree seedlings are grown in deep trenches provided with necessary lighting. Thus, they are not affected by the wind and the hot baking sun on the ground surface, and the vegetation grows and flourishes in the humid and still air environment deep in the trenches. This method also inherently resolves the common problem of the inability to achieve deep root growth of the seedling in a desert area.

[0005] (3) Another method is placing healthy tree stocks or seedlings in a bullet or bomb or bullet head for planting. A helicopter is used for carrying out such rapid planting even in areas inaccessible by land means such as up on steep mountains, and areas inhabited by ferocious animals or poisonous creatures. With the present invention of the century of the unique planting method, forestation may be carried out in any area throughout the world such that in the future a photograph of the globe taken from the outer space would show a much greener world.

[0006] I remember before I was of the age to enter primary school, there was a pail of sand in front of every household, which was intended for extinguishing fire in the event of an air attack by enemy airplanes. My nephew and I threw some seeds of fruit which we had consumed, into such pail of sand; and to our surprise, after several rainfalls, some of the seeds sprouted and grew into seedlings. I realized then that plants could grow on sand when it has water. Also, my sister told me that there were many deserts throughout the world which could not be cultivated for vegetation because of the lack of water and their extremely hot weather condition; and one might die from heat exhaustion by walking through a desert. I then realized the hard life that people living in or around a desert must endure; and I admired their perseverance under such hard environment. In my tender age, I wished I could help them in some way to overcome such hardship. Another event that prompted me to think further about this matter was that, during the hot summer weather, people needed pails to carry water from wells and rivers to their homes. Some farmers could not afford to purchase water pails since they were unable to grow rice to earn money due to the lack of rain in the summer season. I thought the solution would be to build a casino to earn the money required. When a casino is situated in the desert, roads would be built to reach it, then people may go through the desert in the roads. It has been 58 years since then. Now, there are homes, casinos, and hospitals built in cities in forested areas located in a desert.

[0007] The deterioration of the global weather is largely due to the negative effect of the ever increasing demands for advanced living standard by human. The global greenhouse effect has now already caused a variety of natural disasters to occur. This is mainly due to the build up of large amount of carbon dioxide gas created in the atmosphere, which causes the adverse changes in the global weather. Human has not yet invented a tall enough tower with escalator so that bags of carbon may be carried out into the universe for disposal. We rely mainly on strong trees to absorb the carbon dioxide gas from the atmosphere. However, the global economy is more in favor to big corporations making huge earnings by cutting down trees rather than in planting more trees. With the increasing number of automobiles and the decreasing number of healthy trees, green forested areas are diminishing in all countries around the world. This is particularly true in the poorer countries, but it is still not much better in the richer countries. With the ever increasing size of the hole in the ozone layer and the more frequent occurrence of natural disasters, it is ever more urgent to utilize the sand and soil diligently according to the present invention to cultivate for more healthy trees.

SUMMARY OF THE INVENTION

[0008] 1. The invention begins by studying and solving the most difficult problem in the forestation of the desert. The most difficult problem with sand is that there is no cohesion in the particles in sand, for this reason, it is easily scattered by wind. Thus, it is difficult to cultivate vegetation in sand. An attempt has been made in the Middle East to spray a thin layer of crude oil on sand to increase its cohesion so as facilitate cultivation; however, it has not been proven to be feasible. The present invention utilizes the readily available sand in the desert and vacuum filling it in bags formed by automation, which consist of two flexible plastic sheets. The basic material includes a mixture of sand and soil, yellow soil, red soil, clay soil, and fine gravel etc., rather than using the expensive common molded clay brick, rock, and fire baked clay brick. The basic material may be taken from the desert without requiring further effort in searching for any particular chemical ingredient, size, cohesion or retraction. It is not necessary to build a factory at the site or use precious natural resources such as coal and mine in the process that would create pollution to the environment All that is necessary, is a farming cultivating machine or tractor, separating large size rocks from the finer sand and soil, a back hoe machine, and the formation of flexible plastic tubes or bags of various shapes. The basic principle of the present invention is to utilize only the natural material from the earth to cure its sickness. The unique flexible bricks of the present invention may be provided in various shapes and sizes as shown in FIGS. 5, 5B, 5C and 5D, depending on the functions required. For example, elongated flexible bricks of different sizes are used for constructing barrier walls for a long distance in a desert. The flexible bricks may be fabricated in a continuous process on site with the fabricating machine driving behind the cultivator or tractor which disposes of unsuitable large size rocks along the path. The vacuum device on the fabricating machine extracts air from the flexible bricks while they are being formed so as to form a vacuum pack. The lifting device in the fabricating machine delivers the flexible bricks along the two sides of the path as well as piling them to a desired height to form barrier or retaining walls. With the fabricating machine and the cultivator driving in such tandem manner, barrier walls such as wind barrier walls may be conveniently and quickly built anywhere in the desert. The method may also be used for installing dikes along a river such as the Yangsi River in China which is prone to flooding. As shown in FIG. 5. The flexibility of the flexible brick of the present invention, facilitates flexible dikes to be built, which can migrate between high tide and low tide to maintain their flood prevention function. A barrier may also be built with such bricks across a river such as the Yellow River in China to form dams and lakes for saving water and separating the sediment from the water. No reinforcing steel or concrete foundation is required in building the walls and dikes with the present unique brick since it is desirable to have the flexibility characteristics.

[0009] The brick is conducive for grass root growth and for use by farmers, and it has the advantage that it may be installed freely and easily at any location, such as along the banks of a river or stream to prevent water erosion. Thus, the fabricating machine of the present invention as best shown in FIG. I may be used to build dams, flood dikes, islands in shallow beaches, or retaining walls along a sea shore. Leakage or sand and water from the bag is prevented by a plurality of “/\” shaped flaps located in a reverse flow control venting port in the plastic bag as shown in FIG. 5E. The flexible brick may be used to grow various types of vegetation. It is capable of retaining an amount of water equal to 30% of its own volume within the bag, accordingly, it is beneficial for the vegetation growing in such bricks since the amount of water retained in the bag in one rainfall is equivalent to five times the amount of water retained by the same amount sand outside of the bag.

[0010] 2. Another important method is growing vegetation within a tent-like housing or shield having a

[0011] water supply control as shown in FIG. 6. The housing or shield is made of a plastic sheet painted with a sun light and heat reflection external coating. A wind operated device is provided for supplying fresh air within the housing as shown in FIG. 6. The plastic housing has a predetermined height to protect the vegetation or tree seedling to grow safely to such height. Eight telescopic support rods, similar to fishing rods, are located around the base of the plastic housing and are inserted to a desired depth into the sand to anchor the housing securely on the sandy ground. The completed sealed housing is thus erected on the ground and it is weighed down safely by the weight of the sand located within it. In turn, the sand within the housing is protected by the latter. Thus, a green house is provided by the housing for growing the seedling in a tropical rain forest like environment to a healthy tree. In the meantime, grass may also grow around the tree to hold the sand particles firmly together. A cutting blade ( No.70 in FIG. 6A) is located at the top of the housing which would sever the housing when the tree has grown to such height particularly when it is also swayed by the outside wind. The bottom of the housing would also be eventually destroyed by the roots of the growing tree. An air inlet (No. 51 of FIG. 6) is provided for supplying fresh air into the otherwise completely sealed housing. A ventilation opening (No. 60) is provided to save every precious cubic centimeter of water from the moisture within the housing for the plant growth. A unique sun light operated water pump (No. 55) is provided to extract water from the ground through tubing (No. 58) to supply the water required for the growing tree. The sand within the housing retains an amount of water equal to 30% its volume. A water storage tank (No. 47 in FIG. 6) is mounted at the middle of the outer side wall of the housing for supplying additional water to the interior of the housing. Leaf shaped collectors are provided for collecting rain water to the water tank. To safe guard against water shortage in a severe dry condition, a plurality of water balloons are located in the sand within the housing around the seedling. Each water balloon is provided with an automatic cutting blade on its surface. The cutting blade is automatically operated by a retractable tissue material such as cow tendon which reduces its size or length as the humidity of its surrounding decreases. Thus, the water balloons will be severed under hot dry spells which may occur up to several months without rainfall in the desert Water balloons with cutting blades having the retractable tissue material of various lengths are provided such that they will be severed at different times in order that water from the different balloons will be used to provide the required emergency water supply over a long period in the hot dry spell. A plurality of water containers are placed on the closed bottom cover of the housing. The water level in the water containers is controlled by a floating cantilever arm(No. 50 in FIG. 6) similar to that used in the water tank of a common flush toilet. A plurality of openings are formed on the sides of the water containers such that the water may flow out from these openings into the interior of the housing. Water is supplied to the water containers by tubes 50A from the water storage tank (No. 47) and the flow rate of the water is controlled by the floating cantilever arm. A plurality of cutting devices (No. 69) are located at the bottom cover. These devices will be pushed by the roots of the tree when it has grown to maturity in about 10 years to break the bottom cover of the housing when it is no longer required. A large plastic cloth having a diameter much larger the base of the housing is placed on the ground outside of the housing to the bottom of a circular trench dug in the sand surrounding the base of the housing. The trench is for collecting water from any annual heavy rain fall in the desert. The water collected will eventually seep into the ground to feed the tree. This method may be employed in the most severe desert condition for growing vegetation.

[0012] 3. In a semi-desert region, vegetation may be grown with the design as shown in the sectional view in FIG. 13. This design may be employed in a semi-desert region which has a more moderate weather condition and some vegetation has already been grown in it by using the flexible bricks for preventing the sand from being blown away by wind. The interior of the housing is directly open to the outside atmosphere. A plurality of /\-shaped reverse air flow control venting ports ( No.36) are provided to control the humidity of the interior of the cylindrical shape housing which has a lower portion located in a deep trench formed in the sand. The seedling grows in the trench covered by the housing. Optical fibers(No.109) extend from the top part of the housing above the ground to the lower part are provided to conduct sun light to the latter for the growing seedling. Water supply and water collection are provided in the manner as described in the previous embodiment. Since this embodiment is open to the outside atmosphere, it is not necessary to seal the housing or to provide additional fresh air supply as in the previous embodiment. A cap (FIG. 13, No. 108) is provided at the top of the housing. The cap is rotatable by the outside wind to prevent sand from being blown into the housing. The water pump may be operated by the heat of the sun light as in the previous embodiment, or alternatively by a windmill (FIG. 10). Two UV ray reflecting lenses (FIG. 13, No. 111 and 110) are provided in the tubular housing to lower the heat caused by the noon day sun light. These lenses are painted with light reflecting patterns.

[0013] The above embodiment is particularly suitable for growing young seedlings which can otherwise only grow close to the ground surface. With this method, the seedling may grow close to the sand surface inside the trench within the tubular housing, such that by the time it has grown to the height of the outside ground surface, it would have a height of about 3 feet The tubular housing may be made from water-proof paper or thin metal plate similar to that used in making a tin can. Such material will automatically break down and disintegrate in about 2 to 3 years after being used in the humid soil environment which normally exists at the depth of 3 feet under the ground in any desert area. The cap is made by rolling a plastic sheet with glue applied at its joint. The plastic and the glue would also break down over time to separate from the grown tree, and eventually the trench would be filled again by wind blown sand. Therefore, it is not necessary to spend further effect in re-filling the trench with sand. Moreover, since the matured tree is deep rooted when grown with the present method, it would not be easily uprooted by the strong wind in the desert.

[0014] 4. The following method is applicable in a region having annual rainfall more than the semi-desert area mentioned in (3) above. In such area, the embodiment as shown in FIG. 13A may be employed. In this embodiment, the tubular housing may be made with a cardboard material. A plurality of leaf shaped plates are mounted on the side of the housing for collecting rain water or dew for growing the seedling in the housing. A sand cap No. 107 is provided at the top of the housing. A circular opening is formed at the top of the sand cap. The circular opening has an inwardly and downwardly folded lip slanting at 45 degrees; and a plurality of thin metal foils or plates (FIG. 13A No. 109B) are provided on the lip by adhesive. Wind blowing at the housing would cause the sand cap to cover the housing more tightly. Furthermore, due to their slanted position, the metal foils or plates would reflect sun light into the housing to supplement the light provided by the optical fiber. Several water balloons are also located in the sand within the housing. A plurality of wall openings ( No. 120) are formed in the portion of the side wall of the tubular cardboard housing located below ground so that the ground moisture of the surrounding sand and soil may enter the housing through these wall openings. The planting of the seedling in the trench in this embodiment may be carried out automatically with a cultivating machine.

[0015] 5. Bullet planting: In this embodiment, the small seeds of large trees are placed in an embryonic sack (FIG. 20) which is installed in the head of the bullets normally used for the gun on a fighter airplane. The bullet head is made of a mixture of hard wood powder, fiber, fertilizer, water base glue and plant base plastic compacted together under high pressure. The plant seeds are located in a depression or cavity formed in the rear end of the bullet head and it is covered with a mixture of fertilizer and heat refractory material. Planting may be carried out by firing the bullets from a helicopter having a telescopic view of the planting area shown on a display screen so that the bullets may be accurately fired at every square foot of the planting area. The seed may be attached to the bullet head with an optical fiber. Therefore, after a deep bullet hole is formed on the ground by the bullet, the seed would automatically be dragged into the bullet hole by the optical fiber. The impact of the bullet on the ground would cause a small amount of the spout promoting fluid to be released from the mixture to enhance the seed growth; also sun light required for the seed growth is provided by the deployed optical fiber conducting sun light into the bullet hole. In this manner, the seed would grow in a favorable humid condition in the hole deep under the ground without being affected by the strong wind and hot sun on the ground surface. This method is particularly applicable in a more temperate region in which sufficient rainfall would provide the necessary water for the seed growth. After firing, the bullet shells or cartridges may be retained in the helicopter for further use. Furthermore, this method may be utilized for planting in any area even if it is inaccessible by ground means or regardless if it is up in a steep maintain, inhabited by ferocious animals or poisonous creatures, or deep in a river valley. The success growth rate of this method is so high(FIG. 15, 16, 17, 18) that in the future the view of the earth from the outer space would show a lush globe. Several designs of this embodiment are shown below. They function in the same principle but are adapted in various regions having different amounts of rainfall and different soil conditions.

[0016] The requirements for this embodiment are as follows:

[0017] Firstly, after their fabrication, the planting bullets must be safe for storage and are ready for use any time. A small amount of water required for the initial growth of the seed is contained within a separate sealed water balloon which is also packed in the bullet head. The water balloon will break by the impact when the bullet hits the ground to provide the water required by the seed initially. The water balloon, the seed and the optical fiber are located in a depression or cavity located at the rear end of the bullet head (FIG. 15 No. 142) and are protected by a heatproof cover plate. The cover plate will be removed between the time at which the bullet leaves the gun barrel and prior to it hitting the ground, so as to release the optical fiber. An annular steel brush ring is located at the muzzle of the gun barrel(FIG. 21 No. 165) and it is engagable with a channel formed in the bullet head for removing the protective cover plate so as to release the optical fiber from the bullet head. Several other methods to achieve the same result will be shown below.

[0018] 6. Tree planting ball: this embodiment enables planting to be carried out inexpensively and automatically. In a dry and hot region, seeds may be planted deeply in trenches(FIG. 14) in the land having the top layer of its soil initially removed so that the seed may grow in a moist condition deep in the soil. A cultivating machine equipped with a drill is used both for forming planting holes in the soil as well as placing sealed balls containing seeds or pre-dressed seedlings into the holes. Water balloons and plant nutrient fluid are also included inside the balls The seed is located in an embryonic sack located within each ball. One end of an elongated optical fiber is connected to this embryonic sack and the free end of the optical fiber extends outside of the ball to wind around a channel(FIG. 14 No. 124) formed on the outside surface of the ball. When the ball rolls into the hole, the rolling motion would cause the optical fiber to unwind from the channel with its upper end held in place by a spring clamp such that the ball is hung within the hole by the unwound optical fiber which subsequently conducts the sun light from above ground to the seed in the embryonic sack. The lower end of the optical fiber is also connected to a knife which would sever the water balloon. The ball is similar to an egg for incubating the growth. Air is supplied to the interior of the ball through an opening (No. 135). The optical fiber also extends outside of the ball through this opening. The upper and lower halves of the shell of the ball are made of a mixture of fertilizer and a water soluble case or glue or gluten and plant fibers compacted together to form a thin half shell. After more than ten days, the upper half shell of the ball will dissolve and separate from the lower half shell similar to a broken egg shell, some of the water from the severed water balloons would remain in the lower half shell for the seed growth.

BRIEF DESCRIPTION OF THE DRAWINGS

[0019]FIG. 1 shows a perspective elevation view of the flexible brick fabricating machine. The construction of the machine has a rotatable round tub provided with a mold (No.2). The mold is rotated with various gear drives to roll out a round shaped plastic wrapping simultaneously from both the right side (No. 1), and the left side (No.5), towards the center (No. 2). The plastic wrapping No. 1 has the required form and is adapted to engage within a steel channel (No.7)in the mold. Holes are formed on both side edges (No. 16, 20) of the plastic wrapping to engage with teeth on the mold for driving the wrapping. An filling station (No. 4) is located at the top 15 of No.2 for filling the wrapping with sand. The sand is obtained by a scoop (No.26) retrieving sand from the ground and delivering it to the filling station by an elevator (No. 3). After the lower half of the plastic wrapping 1B is filled and packed with sand, the upper wrapping No.5B is placed over it and heat sealed to it to form the bag. Then air is extracted from the bag so as to form the flexible soft brick. In this manner, flexible soft bricks are formed continuously and then laid subsequently over the desert surface to protect the sand, or to build a retaining wall, or for growing vegetation, or for building dams for collecting rain water etc. The system may also be used to fabricate the flexible soft bricks without performing the laying operation at the same time.

[0155]FIG. 13 is a sectional side elevation view of the embodiment of locating a protective housing partially buried in a trench for growing vegetation in the desert. This method is applicable in a semi-desert region or in a desert region in which the sandy ground has already been treated and stabilized with the laying flexible soft bricks on its surface. Seedlings or seeds may be planted in the cool and moist environment in a trench. Optical fiber is used to conduct sun light into the trench and additional light is also provided by thin reflective metal plates mounted on a cap located at the top of the housing. A water pump, operated by a light condensing lens (FIG. 9 ) or a wind operated elastic ball (FIG. 10), draws water from the bottom of the housing to spray water on the seedling. Air is supplied to the housing through a partially opened top cover. A draft cover made of a soft plastic sheet material (No. 107)is placed on top of the top cover, which is carried by any down draft of wind to cover the housing so as to prevent wind carried sand from entering the housing. The draft cover would return to an upright opened position when there is no wind. A plastic lens having a flower petal pattern (Nos. 111, 110) is provided to block the UV ray of the sun so as to reduce water evaporation within the housing. Reverse pointing ducts (No.39) are provided to separate the regulation between the interior and exterior of the trench. The portion of the housing located below ground, in the trench, is made of thin metal plate similar to that used in making a tin can, which will disintegrate automatically after several years and will be naturally absorbed into the soil. The ducts No. 39 are made by rolling flat pieces of soft plastic sheets into the cylindrical shape with adhesive applied at the joint. The adhesive will break down in time to cause the disintegration of the ducts, at which time the tree has already grown to maturity. Life saving water balloons (Nos. 48, 49) as well as water cans (No. 1 15)) are located in the sand to save water and to supply water for feeding the plant in a manner similar to that in the embodiment shown in FIG. 6. Only in this embodiment, rain water collected by the leaf shaped collectors flows directly into the housing. With the above design, the seedling would grow in the deep moist soil to a tree of nearly 3 feet tall having a strong root foundation and extending above the top of the trench. The blowing sand would eventually fill the trench back with sand similar to as if the tree were planted manually. The result of using this method is far better than attempting to grow the plant on the surface of the dry soil which is readily subject to erosion.

The tracks are adapted to engage with a groove provided in the planting machine for guiding the dropping of a row of such balls, one ball at a time, into planting holes formed in the ground. One end of an optical fiber (No. 122) is inserted into the ball through a slot formed in the channel. The optical fiber is connected to an embryonic sack located in the ball. A water balloon is also located within the ball. The shell of the ball is made of a mixture of fertilizer, fiber and water soluble glue. The ball is dropped into a hole previously formed on the ground by machine such that the ball will lie inside the hole suspended by the stretched out optical fiber.

[0192]FIG. 15 is an isolated sectional side elevation view of the tree planting gun bullet (“A” shaped) used for planting trees in a drought! or planting trees in regions in which water is depleting in rivers, darns and other water sources, or planting in eroded soil after a flood. It replaces the past method of having to carry the seedlings with back sacks to plant them one by one manually. This unique method of planting trees by bullets is important for improving the deteriorating environment around the world and the existence of the human race. The method is by placing a pre-dressed seedling in an embryonic sack with an optical fiber connected to it and it is then installed in a cavity at the rear end of a bullet. The installation is sealed with a heat resistance round plate (No. 142). The other end of the optical fiber is attached to this heat resistance round plate so that the optical fiber is stretched during the flight of the bullet and it is subsequently used to conduct light into the bullet hole formed in the ground. A steel wire brush is located at the muzzle of the gun, which operate to pull the optical fiber out from the bullet as it is leaving the muzzle. The outer shell of the bullet head is made of a mixture of hard wood powder, fiber and water soluble adhesive compacted together under high pressure. It will disintegrate and dissolve in water. Steel is incorporated at the tip of the bullet head to enhance its piercing strength. The planting bullets are fired from a helicopter with a planting gun and the locations for planting may be accurately determined by the operator viewing a telescopic image of the ground displayed on a video screen. The optical fiber will be pulled out from the bullet head after the heat resistance plate has been removed by the steel wire brush. The umbrella like plate will float in the air like a flower pollen just above the ground after the planting bullet has entered the bullet hole so that light is conducted to the embryonic sack in the hole by the optical fiber. The water balloon is also broken by the impact. Due to the differences in soil characteristics and the amount of rainfall, the bullet head may have different constructions; however, the use of the removable heat resistance plate and the working principle remain the same regardless of whether an air gun or water gun is used to fire the bullet. The present system illustrates one example for tree planting. The present bullet planting method enables seeds to be planted anywhere and it meets the hope of those aware of the necessity to save the earth.

[0193] No. 138 is the bullet head outer shell made of a mixture of hard wood powder and water soluble glue compacted together.

[0194] No. 139 is the inner shell made of a mixture of fiber and high strength water soluble glue compacted together, and it is located over the inner surface of the outer shell 138. Since the “A” shaped bullet head may pierce too deep into the loose sand for growing the seed, it is designed to have a length equal to twice the length if it impacts with water.

[0195] No. 140 is a small diameter extensible inner shell section which may slide upwards until its lower end latches with the second inner shell section so as to extend the length of the bullet head.

[0196] No. 141 is another smaller diameter third inner shell section which is slidable to latch with the top of the second inner shell section. It functions to increase the length of the bullet by three times. “/\” shaped reverse flow regulating flaps (No 39) are provided at its upper portion. These flaps will operate to prevent water from escaping outward upwardly after the water balloon has been broken.

[0197] No. 142 is the heat resistance plate for protecting the optical fiber, the tree seeds, the embryonic sack and the water balloon from the force and heat of the explosion in the bullet. Its diameter is equal to the rear end of the bullet head. Adhesive is provided in a round groove formed in the plate to attach the head of the optical fiber to it as well as attaching it to the bullet head.

[0198] No. 143 are holes formed around the side of the heat resistance plate.

[0199] No. 144 is the bullet cartridge similar to that commonly used in military bullets.

[0202] No. 138A is the metal protective head.

[0203]FIG. 16 is a sectional side elevation view of the A shape bullet after it has hit the ground.

[0204] No. 147 are holes formed in the side of the cylindrical shell for admitting rain water into the shell or expelling water therefrom.

[0205]FIG. 17 is a sectional side elevation view of the B shape bullet head. A characteristics of this type of tree planting bullet head is to use another method in removing the heat resistance plate and in pulling the optical fiber outwards. As shown by the reference numeral No. 145A in the drawing, small air holes are formed in the circular plate. These holes are inlets of a circular tunnel(No. 145B) formed by matching a circular groove formed on the plate(No. 145A) and a similar circular groove is formed in the bullet head (No. 151). Compressed air from the explosion of the gun powder would enter the tunnel to separate the heat resistance plate No. 142C from the bullet head. Therefore, it is not necessary to provide a steel wire brush at the muzzle of the gun to provide the same function. The water balloon has a annular shape and it is located within an annular hollow cavity in the bullet head wall. A sharp pin(No. 149) is located at the bottom of the annular hollow cavity, which will break the water balloon when the bullet hits the ground.

[0276] The advantages of the present invention are as follows:

[0277] 1. Human must use their intelligence and logic to carry out reforestation and elimination of the harmful effects and consequences of the previously discussed soil erosion due to water erosion and sand storm. Use of reinforced concrete and sand dykes can not prevent water erosion completely. More importantly it must be remembered that running water in streams results from accumulation of droplets of rain. Water saving and preventing water soil erosion must be addressed at the same time. Land scatters widely but it all belong to us, to the grass roots and to the farmers. Reinforced steel concrete dams are built at selected fixed locations, they belong to those locations, to industries, and to the engineers. Sand and soil are basically heavy in weight; however, they may be eroded by water and wind to cause disasters. Utilizing such primitive resources to make building material is really a precious approach. The present invention based on such principle to create the flexible soft brick fabricated by holding the primitive natural material on earth with plastic bags produced with advanced technology in order to achieve the incredible engineering project for the earth. For example, as shown in FIG. 23 a desert improving vehicle can be used to fabricate a mile long flexible soft brick. It simplifies a complicated process and eliminates the side effect of requiring large monetary investment.(For example, requiring a large loan from the bank). It, based on the above principle, realistically provides the unique method for reforesting the earth

[0278] 2. Reforestation is a goal in protecting water erosion of the sand and soil as well as saving water. Normally, reforestation requires many years of good weather and rainfalls to achieve. The present invention eliminates such long time requirement. The method may be carried out immediately daily to provide protection of the soil and to save water, the result is equivalent to the benefit which can only be provided by ten-year old matured trees. It also provides protection of the newly planted trees and grass from harmful natural phenomena so that they may grow safely to maturity.

[0279] 3. It provides an industrial mass production process for planting trees in a large scale. It improves production while reduces pollution of earth's important resources, and helps to reduce the greenhouse effect, and the threat of bad changes in the weather.

[0280] 4. From now on, fertile lands are no longer cut off by deserts, and it is not necessary to move Beijin to the south to avoid the sand storm.

[0281] 5. The inventor thanks God for granting him the wisdom to create such easy method for curing the survival problem of the earth. In view of the importance of wisdom and education, the inventor is willing to devote 30% of the profit derived from the present invention to students of poor families towards their education, whose parents are unable to afford such expenses. The whole amount to be used to supplement the school expenses and the student's living expenses. Another 20% is to be devoted to poor seniors.

[0282] 6. To address the problem that government may not afford to finance the present high efficiency tree planting process, and commerce may not be interested in doing so because of little financial return, I think the method may be tried by plant trees in the mountains in Indonesia and Thailand.

[0283] 7. It manufactures building material with low demand natural material that reduces pollution, and using the material to solve the earth's problems because of soil erosion and loss of water resource.

[0284] 8. It attracts more investment from the city dwellers, and encourages villagers to save more of the water resources for their livelihood and to prevent flood, and it also creates more works in the villages.

[0285] 9 It may cooperate with the modem advanced engineering techniques to formulate the method for eliminating the cause of flood disasters.
